We explored how Saccharomyces boulardii might help prevent liver damage caused by Salmonella Enteritidis, a common foodborne pathogen. Using a mouse model, we noticed that pretreatment with S. boulardii significantly reduced the translocation of Salmonella to the liver by 96%.
Additionally, this treatment decreased inflammation and lesions associated with liver injury. These findings suggest that S. boulardii can be a powerful ally in protecting our livers against food poisoning caused by Salmonella Enteritidis.

Postbiotic reduces Salmonella in pullets
We evaluated how a postbiotic derived from Saccharomyces cerevisiae might help reduce Salmonella Enteritidis in young layer pullets. In our study, we tested two groups of pullets—one group received a diet supplemented with the postbiotic, while the other did not.
After introducing the bacteria, we found that while all birds had Salmonella presence, those on the postbiotic diet had significantly lower levels of the bacteria. This suggests that including Saccharomyces cerevisiae could offer an effective strategy for enhancing food safety before harvest.

We investigated the effects of the probiotic Saccharomyces boulardii on infections caused by the foodborne pathogen Cronobacter sakazakii. Through a series of tests, including analyses of cell viability and inflammatory responses, we discovered that S. boulardii significantly improved the health of infected cells. It notably reduced inflammation and the damage caused by the bacteria in both human cells and newborn mice. These findings suggest that S. boulardii is a promising option for protecting against and treating infections related to C. sakazakii.

Effective for recovery

Boulardi saccharomycetes are a must-have at home. They helped my father after antibiotic-associated diarrhoea due to his heart attack; I administered it every three hours, and he stabilised. I also used it for a sick kitten and my cat with dermatitis. During pregnancy, I found relief from heartburn with these capsules. They're safe for everyone and should be in every first aid kit.

Saccharomyces boulardii is a unique probiotic yeast that survives stomach acid. They restore gut balance during medication or travel disruptions and are excellent for food poisoning as they help eliminate pathogens. I always have them on hand after antibiotics for a swift recovery.

We explored how Saccharomyces cerevisiae RC016 could benefit gut health and growth in weaned piglets. Through a well-structured study, we divided twelve piglets into two groups: one received the yeast, while the other served as a control. After three weeks, results showed the yeast group had higher levels of protective antibodies and more goblet cells, indicating better gut health. An additional ex vivo model suggested that the yeast may also help reduce inflammation. Overall, S. cerevisiae RC016 shows promise as a feed additive that can enhance animal welfare and immunity.

Yeast reduces Salmonella in vitro
We explored how various yeast-derived products could impact Salmonella Enteritidis survival in rooster cecal contents during in vitro tests. Several yeast treatments showed promise, with four products significantly reducing Salmonella levels by 1 log CFU/mL initially and by 3 log CFU/mL after 48 hours, compared to controls.
However, these treatments did not influence the overall diversity or health of the cecal microbiome, indicating that beneficial effects can occur without disrupting the gut environment. This research underscores the potential of yeast products in combating foodborne pathogens while maintaining gut balance.

Rapid recovery
6 people found this helpful
A must-have in your first aid kit! My son had food poisoning from watermelon, with vomiting and diarrhoea for three days. On the fourth day, my order arrived, and I promptly gave him one capsule. By evening, the vomiting and diarrhoea had ceased. He felt revitalised the next morning! I’ll continue using it as a preventive measure since my son is in kindergarten and takes vitamins, ensuring proper intestinal function for better absorption.
